Welcome to DiskWarrior

Chapter 1: Introduction 11

But the best use of DiskWarrior is for preventative maintenance of your disks. Many forms of di-

rectory damage do not manifest themselves until long after the damage has actually occurred.

You can prevent this damage from escalating by running DiskWarrior on your disks regularly.

DiskWarrior will rebuild your disk directory, eliminating all existing directory damage. The di-

rectory DiskWarrior creates is also optimized for maximum directory performance, and this will

speed up the performance of your disk. You will ﬁnd doing this regular maintenance of your di-

rectories more useful than rebuilding your desktop.

What Is Directory Optimization?

In a directory, there is a logical order and a physical order of the ﬁle and folder information that

is stored. The logical order is based on the name of the ﬁles and the creation order of folders.

The physical order depends upon the available free space on the disk and space within the di-

rectory made available as ﬁles are deleted and added. Creating and deleting ﬁles makes the phys-

ical order less like the logical order as ﬁles and folders are added to the directory where space

is available. Directory searches are performed using the logical order of the directory. As the

physical order becomes less like the logical order, the drive mechanism must move more to fol-

low the logical order.

Nearly everything uses a search based upon logical order to ﬁnd ﬁles, including Find File/Sher-

lock, the Finder, applications that search for their preference ﬁles, applications that build font

menus, and open dialogs. DiskWarrior optimizes the directory, improving the speed of all of

these activities and many more. Other programs may not provide the true directory optimization

provided by DiskWarrior.

Why Alsoft DiskWarrior Is the Only Answer

When you use DiskWarrior to rebuild your directory, it focuses on what you care most about on

your disk -- your data as it is stored in your ﬁles. DiskWarrior rebuilds your directory based upon

the data it ﬁnds in the original directory. If you have journaling enabled, the journal ﬁle may also

be used. DiskWarrior then uses this information to build an entirely new replacement directory

structure. This approach is similar to that taken by FileMaker with its databases and the Finder

with desktop ﬁles. If you crash or otherwise close a FileMaker database improperly, the next time

you open that database, the ﬁrst thing FileMaker does is rebuild the database indexes (the data-

base structure) using the data in the database. When you rebuild your desktop, you are rebuild-

ing the structure of the desktop database. DiskWarrior takes these processes a step further. When

directory data is severely damaged, DiskWarrior scavenges the directory, ﬁnding all the salvage-

able data. It then uses this data to build a new error-free replacement directory, recovering lost

ﬁles and folders as well as making it possible for the disk to appear on the desktop.
